CHARLES P. STANBON, OF LYNN, MASSACHUSETTS.

CHANNEL-FLAP-TURNBNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 607,139, dated July 12, 1898.

Application filed July 201 1896.

To all whom it nuty concern.-

Be it known that I, CHARLES P. STANBON, a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Channel-Flap-Turning Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to channel-fiap-turning machines wherein the flap of a channeled shoe-sole is opened up, turned over, and pressed and flattened out in such a position that the stitches which unite the sole to the upper may be readily placed within the channel; and its object is to improve the construe-- tion of the machine and to render it positive and accurate in performing the work which it is designed to do. i

To this end the present inventionconsists of the devices and combination of devices which will be hereinafter described and claimed.

My invention is illustrated in the accompanying drawings, in which similar letters of reference refer to similar parts throughout,

. and in which- Figure 1 is a side elevation of the left-hand side of the machine. Fig. 2 is a front view thereof. Fig. 3 is a section upon the line X X in Fig. 4, looking down, part-s being in plan. Fig. 4 is an elevation of the right-hand side of the machine. Fig. 5 is afragmentary sectional view illustrating a detail of construction.

In the machine shown in the drawings, A represents the frame of suitable shape to support the working parts. Frame A at the top is provided with bearings B, in which is mounted the driving-shaft O. Driving-shaft C has fixed'thereto, preferably between the bearings B, the pulley D, said pulley being driven to actuate the shaft 0 by a belt from any suitable source of power. Shaft G at its ends has affixed thereto the bevel-gears E and E, which respectively impart motion to the channel-flap turner and feed-wheel, as will be hereinafter fully described. I

Frame A at its front end is provided with bearings 13, in which is mounted the vertical Serial No. 599,967. (No model.)

tool-shaft Z), which at its lower end carries the channel-flap-turningtool c, which may be of any usual or preferred form, that shown in the drawings being provided with a series of suitable means, those shown comprising a bevel-gear cl, fixed to the tool-shaft b, in position to mesh with and be driven by the bevel-gear E on the driving-shaft 0.

Attached to the bearing- 13 or some other suitable portion of frame A is the presserfoot 19, which may be of any usual or suitable construction, the lower end of which bears upon the upper surface of the work during the operation of the machine.

I will now proceed to describe the mechanism for yieldingly sustaining the work in contact with the tool 0 and for feeding it along beneath the same.

F represents a frame or carrier which is pivoted at its rear end upon a stud P to the frame A and which is provided with bearings g, in which is mounted the shaft 9. Shaft gat its rear end is provided with a worm-wheel h, which meshes with the worm 7L, fixed upon the lower end of the short vertical shaft 1, which is mounted in bearings B of frame A, motion beingimparted to said shaftlby bevelgear M, which meshes with bevel-gear E on shaft '0.

Frame F at its forward end is provided with a head-piece H, in which is fixed the inclined stud 8, upon which is mounted and free to rotate the feed-wheel 10, said wheel having the serrated or milled edge, as is usual in these machines. Feed-wheel-w is rotated to feed the work by the pinion o, fixed upon the forward end of shaft 9, meshing with the gear I, attached to or formed on the under surface of wheel 10. In order to yieldingly sustain the work in contact with the presser-foot p and tool 0, the frame F, which carries the feedwheel, is acted upon by the spring 0, said spring bearing at one end against a nut or collar 0, which is secured to the end of a depending rod 0 secured to the front of frame A and at its other end against the headI-I or a collar or washer t surrounding said rod and resting against said head. The true vertical movement of the head II and the feed-wheel w is insured by forming a slot II in the rear face thereof, in which fits a guide or projection 11 upon the frontof frame A. Head His also provided with a tubular sleeve or extension H surrounding the rod 0 within the spring 0, which insures a smooth bearing and free action of said spring. The tension of the spring may be adjusted by turning the nut O and moving it along the rod 0 For the purpose of adjusting the space between the tool 0 and the feed-wheel w to accommodate soles of different thickness, I pr0- vide an adjustable stop to limit the upward movement of the feed-wheel. This stop may conveniently consist of a set-screw q, set into an ear or lug q upon the side of frame A, said screw being held in its adjusted position by the jam-nut g Said set-screw bears upon the pivoted frame F, and thus limits the upward movement thereof and of the feed-wheel in, carried thereby, caused by the. spring 0. The machine may have any usual or preferred form of channel-gage to fit into the channel and guide the sole, and I provide in addition thereto a suitable edge'gage to bear upon and guide the edge of the sole as it is fed beneath the tool 0.

The edge-gage e is shown in Figs. 2, 3, and 4, and comprises the forward laterally-curved blade having a cylindrical or other form of shank e, fitted to be freely adjustable in a bearing e which may be formed on or attached to the front of frame A.

The gage c is held in its adjustable position by a set-screw a which is mounted in bearing 6 and bears at its end upon the shank e of said gage.

By making the edge-gage adjustable, as shown, the position of the edge of the sole and the channel-flap can be accurately fixed and the work of the machine rendered more positive and certain, and the work of turning the ehanneLflap can be easily accomplished whether the channel be at or near the edge or at some distance therefrom.

In these machines as heretofore constructed there is great danger of the edge of the sole coming in contact with the mechanism for rotating the feed-wheel, causing damage to the work and oftentimes clogging and (1amaging the machine. To obviate the objections noted, I have provided the guard or table '6, which comprises the base or arm 29, secured to the swinging frame F by means such as the screws i and which extends upwardly and laterally in the rear of the feedwheel w a sufficient distance to cover the pinion 0 and gear if, thus removing the liability of the edge of the sole coming in contact with said gear-wheel t. The guard or table t is cut away at t, as shown in Fig. 1, in order that it may cover the pinion o and gear t without interferin g with the rotation of the feed-wheel 20.

To depress the swinging frame F against the tension of spring 0 for the purpose of inserting the edge of the sole between the feedwheel w and tool 0, the usual treadle-actuated ,rod (not shown) may be connected to lug r and operated in the manner common to these machines.

The operation of my machine is as follows: The stop 1 having been set to accommodate a sole of the desired thickness and the sole being in position between the feed-wheel w and tool 0 and power being applied to the shaft C, the connections between said shaft (l and the tool-shaft b and feed-wheel shaft 9 will cause these shafts to rotate, and thus to cause the feed-wheel w to move the sole beneath tool 0, which operates to turn over and smooth out the channel-[lap in the ordinary manner, the sole being meantime guided by the edge-gage e, as heretofore described.

Having fully described my invention and its mode of operation, I claim as new and desire to protect by Letters Patent of the United States In a channel-iiap-laying machine, the combination with a rotating channel-flap-laying tool, of a rotating work-supporting feedwheel, connected mechanism for actuating said tool and feed-wheel, a spril'ig-sustained swinging frame upon which said work-support is carried, an adjustable stop limiting the upward movement of the swinging frame, a slotted head on said frame, a guide projection on the fixed frame of the machine, engaging the slottcd head to guide the same, a table or guard carried by the swinging frame and curved upwardly and laterally along the feed-wheel and an adjustable gage, all arranged and operating, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

CHARLES l. S ANBON.
